# Using MAPLE

We upgrade to the current version of Maple each summer at Villanova University working with Maple worksheets with file extension .mw which have a clickable calculus interface with a complete range of palettes for creating mathematical symbols and typesetting mathematical documents, context-sensitive right click menus to perform most of the usual mathematical tasks to the outputs of expressions or equations that we input into Maple, as well as many tools and interface facilitators that make it easy to do many activities without knowing syntax or commands.

Clickable calculus allows users to create 2-dimensional mathematics expressions in standard mathematical notation seen in textbooks [except for more strict function notation: cos(x) instead of cos x]. When these expressions are entered into Maple and evaluated, they produce output which can then be acted upon by right-click menus, allowing most elementary needs to be accomplished without knowing the command syntax (which can also be entered character by character as seen in Maple codes in textbooks which assume the classic interface).

### WYSIWYG input, palettes, right click menus

A variable width leftcolumn frame in the Maple worksheet window has numerous expanding palettes to insert input in standard math notation (Maple 2d notation as opposed to Maple 1d notation, i.e., Maple commands) into the input regions that makes it very attractive to use now for students and instructors, since one only needs to be able to do standard Windows clicking, tabbing and choosing to achieve most of the goals needed for the calculus, differential equations and linear algebra sequence. Right clicking on output expressions offers a long list of choices of operations one can apply to that expression.Once can mouse drag the palletes to the top which are most useful for our university mathematics: Expressions, then Common Symbols, then Calculus, then Matrix, leaving the first two open for ready use.

The Tools Menu gathers together for easy access all the extremely useful interactive tutorial applets commands and example task worksheets for calculus and linear algebra.

You can probably safely ignore the rest of this web page.

### Opening worksheets on the web and email attachments

If you have Maple delivered through your Windows operating system as a local or networked application, other programs like web mail (attachments) or Internet Explorer (URL links on web pages) will know how to open it as a Maple worksheet automatically through its file extension. However, the Outlook webmail used by faculty when they are away from their primary computer, does not allow Maple attachments to be extracted properly (they are saved as empty files) and these files must be zipped before attachment by right clicking on their filename in Windows Explorer and selecting Send to Compressed (zipped)  Folder. However, Maple worksheets attached to Outlook webmail messages are extracted properly from the Outlook client email used by all faculty on their primary computers, and by all students using the Gmail Villanova Student Email platform.

If you do not have Maple installed locally or on your network (so you must use Citrix delivered Maple), Windows will not know how to open the worksheet attachment or a web link to a worksheet. [You can open the worksheet in WordPad so you see the underlying code and not the GUI interpreted worksheet, which is not very helpful. Maple .mw worksheets are to Maple like .htm documents are to Internet Explorer or any browser, namely just ordinary text files of at first confusing code called XML from which the software creates a screen image that you see.]

To open the file with Maple, you may have two options:

• Save the file and open it outside the application by then opening Maple and using the File Menu Open File command to find it, which it can only do if the file has the correct file extension.
• In Internet Explorer, copy the URL of the linked worksheet and then open Maple and use the File Menu Open URL command to directly open the file from the internet, which is much quicker than first saving locally the file. You should then save it locally if you make changes.

In Internet Explorer when you right click on the link to savea worksheet,be sure to keep the file extension ".mw" or Maple will not "see" the file when you try to open it using the File Menu, Open selection in Maple, or by double clicking on the file in Windows explorer.

Use a single user local version of Maple if possible!

If you are using Citrix supplied Maple through the web [i.e., not as a local windows operating system application] and choose to save a file locally, then you must save worksheets from the web to your C:\ drive or to a  local networked folder and open them separately in Maple. Citrix does not see your local My Documents folder or your Desk Top; its own My Documents and Desk Top folders are on the remote server under your user profile.

### Citrixweb use of Maple [last resort]

The Citrix application delivery works with the usual browsers. See
